Abstract:
BACKGROUND:Distal tibial tuberosity-high tibial osteotomy is a surgical treatment for knee osteoarthritis,but there is still a lack of clinical studies on its effect on ankle joints. OBJECTIVE:To observe the effects of distal tibial tuberosity-high tibial osteotomy on ankle angle on coronal plane of the radiography of the full length of lower limb in weight loading. METHODS:Data of 40 patients(41 knees)with distal tibial tuberosity-high tibial osteotomy from March 2021 to March 2022 were retrospectively analyzed,including 31 females and 9 males,20 left knees and 21 right knees,aged 49-75 years,mean(63.44±6.57)years.The radiographic data of the full length of the lower limb in weight loading were collected before,week 2 and week 48 postoperatively.Hip-knee-ankle angle,talar tilt angle,tilt angle of the ankle,tibiocrural angle,and tibial articular surface angle were measured before and after surgery. RESULTS AND CONCLUSION:(1)Hip-knee-ankle angle improved from(-6.24±3.69)° before operation to(2.59±3.49)° week 2 postoperatively and(2.15±3.49)° week 48 postoperatively.The tilt angle of the ankle changed from(-7.90±3.11)° before operation to(-2.51±2.59)° week 2 postoperatively and(-2.46±2.42)° week 48 postoperatively,with statistically significant difference(P<0.001).(2)There was no significant difference in talar tilt angle,tibiocrural angle,and tibial articular surface angle before and week 2 postoperatively.(3)No significant difference in the angle changes was detected between week 2 and week 48 postoperatively.(4)It is indicated that distal tibial tuberosity-high tibial osteotomy can not only correct genu varus but also improve ankle angle.This result remains stable after 48 weeks of weight-bearing activities.
